Please help me to solve this.
Graylog version - 2.4.6

to be honest - the first error is from the collector sidecar - not mongodb.
What is your issue, how did you have installed, what have you tried to solve your problem?

In this case, the Sidecar is telling you it cannot talk to the Graylog server you specified as the source for collector configuration. That could be a networking issue, or because the Mongo backend is missing 😉
The problem with Mongo is clear as day:
`exception in initAndListen: 29 Data directory /data/db not found., terminating`
When you installed MongoDB you did not create the data directory.
